At home I often send the DI out of the Cab M+ straight into a powered studio monitor, so I can play at low volume whith the DynIRs making it sound good anyway.
A sound comparison with the LePreamps would be nice. I'm aware that it is more than just the three in one box, but a comparison of the similar functions would be great.
In WoS you do it by choosing the same cab twice, correct. In Torpedo Remote you can only use one cab at a time, but you can give it two mics. There's a tutorial I like (a bit old now).
The first number 9 preset is the preset you have saved. The second one (*) is a non saved modification to the first one. It will disapear next time you make any changes to any preset (or if you save it, of course).
The correct link to the manual is (I believe):
https://wiki.two-notes.com/doku.php?id= ... r_s_manual
It will certainly get corrected soon, but the link on the CAB M+ side still goes to the CAB M.
( The link on https://wiki.two-notes.com/doku.php?id=start lacks the second "plus").
I don't know the real answer to your question, but for the time being you can get some of the sound by having one (or two) of the mics far from the speaker. Well, you had probably thought of it already, but...
You can use two mics only when the cab is downloaded to the device (at least with CAB M). So buy the cab, download from computer to device and you can use two mics. Applies to all the cabs (all I've tested at least).
Recommend testing the SuperBlue ;) A favorite of mine.
